My inve tion relates to amusement*devices and my object isto `provide acomparatively simple andinexpensive device ot thischaracter having acombinedrotary and toeter action. t i

Another object .istoy provide an amusement device which may hey opeatedby the moven'ientoi the bodies of the pas igers, so that the costei?}.n'o.viciing and maintaining motor tor that purpose may be avoided,thereby rendering the device especially suitable tor use on public playgrounds,

A further object is-to provide a device oit' this character otsubstantial construction so that children playing)` thereon are notlikely to become injured through breakage et' any ot the pars. l K

ther objects will hereinafter appear, and in order thatI the inventionmay be fully understood reference will now be had to the accompanyingdrawing in which:

Fig. 1 is a side view ot the device with the lower portion thereot insection. I

Fig. 2 is a detail plan view ot'. the upper portion of the devicearranged in a horizonm tal plane.

iig. 3 is a horizontal section on line III-III of Fig. 1. A

Fig. 4 is a horizontal section online IV IV of Fig. 1.

In carrying out they invention, I employ a conical casing 2 provided atits upper end with a socket 4t to receive a ball (3, which is operahlyheld. in said socket by a cap S.

i() designates an inclined shaft provided intermediate its ends with theball' G9 which is tilted to said shaft to support the same. The upperend of said shaft is provided. with a spider-like passenger carrying)`frame 12 consisting of radial members 11iprovided at their outer endswith seats 16, braces 18, and struts 20. The inner or adjacent ends oi"the radial members are united by a coupling' 22 secured to the upper endot the shait 10. The braces 18 are connected at their outer ends to theradial members 1d and at their innercnds to hearing 2t ixedly mountedupon the shaft 10. The struts 2O hold the radial members in unin formspaced relation and areaided in this by connecting rods, tubes or bars2t which unite the seats 16 in pairs as shown by Fig. 2.

Handles 26 are disposed in iront of the seats 16 and liXed to themembers 1li, tor the passengers to hold to.

The lower endof ythe shaft 10 is provided with an-antiirictionroller 28which travels inten annular guide 30 in the bottom of the casino' 2,.andthus. maintains said shaft in an,inclined.positiom y i .In4 prac-ice the`casii'ig 2` preferably sunk to the level of the ground as shown by Fig.1,-v 4 H "irom upsettingand, alsrnto` .n 16 `close to the ground so thatthey can be reailily mounted by children without the aid ot a platform.The casingr 2 is aided in supporting the shait l() and the trame 12 byanchors 32, the lower portions oi' which are embeded` in the groundwhile their upper portions extend through holes in the socket t and thecap 8 and are provided with nuts 34 for holding said cap 8 down upon thehall 6,

Passengers may start the shaift 10 and the passenger carrying 'frame 12in motion by running beside the seats 1G for a short distance whilepushing thereon before vaulting' into said seats. After the passengersbecome seated the motion is continued by said pacsengers leaninginwardly toward the shaft 10 as the seats 16 move upwardly from theirlowermost position, then leaning outwardly as said seats descend. Duringthe course ot the operation the shaft 10 not only revolves lout its endsgyrate or describe orbits about an imaginary axis extending` verticallythrough the center ot the ball 6, the diameter ot the orbital pathsbeing restricted by the roller 28 and the guide 30. The shatt 10 and theframe 12 may also be caused to toeter by shitting the weight in suchmanner as to cause the higher seats to move downwardly and the lowerseats upwardly.

From the Joregoiug description taken in connection with the drawings itwill he ap )arent that the device .not onlv revolves but t 1 also nas aeeterinfr action which ados to the amusement of the children or otherpas.

sengers occupying the seatsr 16.

lWhile I have shown and described the preferred embodiment ot' theinvention, I reserve the right to malte such changes in theconstruction, combination and arrangement of parts as properly tallwithin the spirit and scope ot the invention as claimed.

IIa-ving thus described my invention, what I claim and desire to secureby Letters Pat ent, is:

1. An amusement device consisting of a casing adapted to be set into theground and provided at its upper portion with a socket ment, anantifriction roller mounted uponv the lower end of said shaft andarranged to Vtravel in the channel in the lower' portion of the casing,a ball'fixed to vthe shaft intermediate the ends of the latter-1 andfreely mounted in the socket in the upper portion of the casing, andpassenger carrier means mounted upon the upper portion ofthe shaft. n

Q 'An amusement device consisting of a ball rand socket support, aninclined `shaft in either direction, said shaft being also free torotate axially independently of any orbital movement or vice Versa, akspider fixed at its central portion to the upper portion of said shaftand including radially extending members, seats fixed to the outerportions of said members and through which the occupants ofthe seats canimpart the above-mentioned movements to kthe shaft, and stationarycircular meansr extending around the lower end of the shaft to limit 30'the inclination of the latter.

In testimony whereof I affix my signature.A
